This Cornell robot makes history by walking 14.3 miles and becomes the longest walking bi-pedal robot in history on a single charge!
Ranger, a robot more specialized for distance than BigDog, beat that record by 1.5 miles, walking 14.3 miles on a single charge of its batteries without being touched by a human. Ranger took about 20,000 steps, over three miles, for each penny worth of electricity it used. Ranger was steered with a model-plane remote control. Commands from the remote control twist the inner pair of legs. The walking was entirely controlled by the 6 onboard microprocessors.
Pretty damn awesome if you ask me, I don’t think I even walked that many miles except once in my life in the forests of Humbolt where I almost died from a bear attack.
